It might just be a setting for your specific phone. Perhaps if it is set to "hide ID" then the caller ID service automatically assigns that generic number (instead of showing "blocked"). Look in the manual for your phone or post the model # here and someone might be able to help you find the correct setting.

Actually, when I call a regular phone number, they can see my caller ID.
However, the problem seems to be with 1-800 numbers such as Jott or long distance accounts that need the call ID to function properly.
My phone is a Nokia 3220, but since regular phone numbers can see my caller ID, this is likely not a phone setting issue, but something related to how the network handles 1-800 phone numbers.
If anybody else has encountered this issue, please let me know.

Interesting. When my cell was on Rogers I had the same problem with my LD service - which I access through a 1-800 number. The call history at the LD provider showed a number with a 942 area code - always the same number - but the system wouldn't allow that number to be registered as an incoming number. In the end I programmed my LD PIN into the speed-dial on my cell, with a pause to allow time for the system to respond.
OTOH, I have another LD service accessed via local numbers in various places - and that does work - so it looks like it is the 1-800 that's the problem.
